Built with SCSS, JS and MVC architecture

I tried to apply what I learned from tutorials way back, This app also accepts a valid domain name also made some custom errors like losing connection and incorrect IP and domain names. It also uses your IP at initial page load :)

I'm just new to MVC and JS so I don't know if I wrote both correctly :( and also tried to use OOP xD.

I did not follow the design much coz I want to be responsive as it can especially on mobile version coz the IP details takes too much space, So I decided to tweak it a little bit.

Any suggestions will be appreciated. Thanks ;)
